Deployment (Access2K developer)

I have a simple program that I want to be able to deploy to several people. Some have access to Access 2k or XP so they don't really need the runtime material. But most do not have Access on their computer so I must package with the Runtime components. My questions are these. If I ran a package without the Add Runtime selected is the only difference from running with the runtime is the Runtime folder? Correct? So if I packaged the project again without runtime and deployed it to another folder could I rename one setup to be setupX.exe and just put the complete runtime deployment files and the second setup file on the CD or do I have to include both complete sets of deployment files?
